The invention discloses a multi-interface remote monitoring system, which comprises a master control transmission module and an upper computer. The master control transmission module has eight types of data interfaces which are a path of Ethernet interface, two paths of RS232 interfaces, two paths of RS422 interfaces, two paths of RS485 interfaces, two paths of low voltage differential signaling (LVDS) interfaces, two paths of controller area network (CAN) interfaces, 23 paths of digital input interfaces, 32 paths of digital output interfaces, 16 paths of analogue input interfaces and 8 pathsof analogue output interfaces respectively, and parameters of each interface can be remotely reconfigured in real time. The upper computer communicates with the master control transmission module by the Ethernet. Monitored experimental equipment communicates with corresponding interfaces of the master control transmission module. The upper computer controls or acquires the experimental state of the monitored experimental equipment by the master control transmission module. The system has the superior characteristics of functional modularization, system integration, rich data interfaces, system function reconfigurability, remote monitoring operations and the like.
